commands for typesetting letter undefined on recent TexLive?

[wiebkejahr]

My setup: pdfTeX 3.14159265-2.6-1.40.21 (TeX Live 2020) kpathsea version 6.3.2

Running the following code pops an Undefined control sequence. \eclpersonalinfo error for all the commands starting with \ecl.

Actual CV is typeset just fine.

Most probably you are using an older version of europasscv. The cover letter was added only in the latest 2020-10-31 version, which is now in TexLive 2020. You probably just need to update the package. (TexLive 2020 is now frozen, and the repository might not work anymore: you need to either use the final repository ftp://tug.org/historic/systems/texlive/2020/tlnet-final or, even better, upgrade to TexLive 2021).
